"Development efforts remain on track for production of Model X in the spring of 2015. We anticipate having operational Alpha prototypes ready by next week in order to confirm design intent and Beta prototypes to be ready later this year."

The good news is the alpha prototypes should allow them to begin real testing and start the clock towards delivery. However, reiterating Spring 2015 means Q2, not Q1. It sounds like they'll need more like 8-9 months worth of testing versus my previous 6 month estimate.
